Help Me Understand This Equation

Recommended Posts

Well, without context, it's really impossible to tell what x and p mean. But h-bar is the Dirac constant, and the [math]\Delta[/math] signs mean "change in." So the change in x times the change in p is greater than or equal to the Dirac constant over 2.


I could hazard a guess that p is momentum, but it depends on what p has been defined to be in the context.
